STMicroelectronics STEVAL-IPMNG3Q

Overview

STEVAL-IPMNG3Q from STMicroelectronics is a compact motor control power evaluation board built around the STGIPQ3H60T-H SLLIMM-nano 2nd series intelligent power module, delivering up to 300 W at 125–400 VDC input and supporting field-oriented control (FOC) via three-shunt or single-shunt current sensing with hardware overcurrent protection and IPM temperature monitoring. It interfaces directly with STM32-based control boards via a 32-pin motor control connector.

For engineers reviewing the STEVAL-IPMNG3Q datasheet, STEVAL-IPMNG3Q pinout, STEVAL-IPMNG3Q application, or STEVAL-IPMNG3Q equivalent, key selection considerations include its integrated SLLIMM-nano IPM, triple current sensing flexibility (onboard op-amps, MCU-based, or internal IPM op-amp), Hall/encoder interface support, and compatibility with ST's STM32 motor control ecosystem for rapid FOC development.

Technical Context

The board implements a 3-phase inverter stage using the STGIPQ3H60T-H IPM - a full-molded IGBT module with integrated gate drivers, bootstrap diodes, undervoltage lockout, smart shutdown, NTC-based temperature sensing, and a single internal op-amp for current feedback. Its fault signaling (T/SD/OD pins) enables hardware-level protection coordination with host MCUs.

Current sensing supports three configurations: dedicated on-board TSV994 op-amps per phase, external MCU ADC sampling of conditioned signals, or direct use of the IPM's internal op-amp output (OPOUT). The board provides configurable shunt resistor networks and jumper-selectable biasing for Hall/encoder inputs (A+, B+, Z+), enabling precise rotor position acquisition for closed-loop control.

FAQ

Is STEVAL-IPMNG3Q compatible with all STM32 Nucleo boards?

No - it is specifically designed to interface with ST's STM32-based motor control evaluation boards (e.g., X-NUCLEO-IHM07M1, X-NUCLEO-IHM08M1) via its 32-pin motor control connector. Direct Nucleo board compatibility requires an adapter or custom wiring due to pin mapping and voltage-level mismatches.

Does the board support both sensored and sensorless FOC?

Yes - it provides Hall/encoder inputs (A+/B+/Z+) for sensored FOC and supports three-shunt current sensing with fast signal conditioning for high-bandwidth current loop closure required in sensorless FOC implementations using back-EMF or observer-based estimation.

What is the role of the STGIPQ3H60T-H IPM on this board?

The STGIPQ3H60T-H is the core intelligent power module: it integrates six 600 V/1.8 A IGBTs, gate drivers, bootstrap diodes, fault protection logic, temperature sensing (NTC), and one internal op-amp. It handles high-voltage switching and protection autonomously, reducing MCU firmware complexity and improving system safety.

Can the current sensing configuration be changed after assembly?

Yes - the board supports reconfiguration via solder jumpers and DIP switches (SW1–SW3, SW17) to select between single-shunt and three-shunt topologies, and to route current feedback either to onboard op-amps, MCU ADC inputs, or the IPM's internal op-amp output - enabling hardware-level adaptation without PCB redesign.
